FIG. 5.

Comparative genomic organization of the tca locus in the different Photorhabdus strains W14 and TT01. Note that the entire W14 tcaABC operon is deleted from the equivalent location in the TT01 genome but that a tcaC-like gene is found at a different location in the TT01 genome, next to a copy of tcaAB with an internal deletion. This suggests that the tca operon is mobile and can occupy different genomic locations in different strains. See the key in Fig. 3. Sequences are from GenBank accession no. AF346497 and World Intellectual Property 02/094867.
